The invention discloses a silicon carbide foam carrier-containing noble metal catalyst, which consists of the following components in percentage by weight: 0.01-5.0 percent of active ingredient, 0.1-15.0 percent of auxiliary agent and 80-99.89 percent of composite carrier, wherein the composite carrier consists of silicon carbide foam and a coating material which is combined on the silicon carbide foam; and the weight ratio of the coating material to the silicon carbide foam is 0.001-1:1. The catalyst has higher mechanical strength and good heat conduction performance, and is particularly suitable for intense endothermic reaction and strong exothermic reaction. The invention also provides application of the catalyst to catalytic reforming reaction; and by using the catalyst of the carrier of the novel structure, the defects of wear of the conventional catalyst and noble metal loss caused by adoption of a moving bed as equipment in the continuous catalytic reforming reaction are overcome, and the problems such
